PAW Tutorial

This tutorial gives an overview of the PAW functionalities. It is organised around four main topics:

• Vectors
• Histograms
• Ntuples
• Miscellaneous

Each example is linked to the next one. It is better to scan the examples in the proposed order.

A printable PostScript version and a compressed tar file of all the examples are also available.
